Answer:
$15
Step-by-step explanation:
Set up a proportion where x is the clearance price of the $40 shirt:
= 
Cross multiply and solve for x:
32x = 480
x = 15
So, the clearance price is $15
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
First find the common factor of -30 and 75, which is 15.
Next find the common factors of the variables:
The factors of x$6 is x*x*x*x
Factor for y is y
Factors for Z^3 is z*z*z
Factors for Z^2 is z*z
The GCF would be x^4z^2
Final answer = 15x^4z^2
1) domain of the first is ( R ) because of its root(3) and its range is (R) because of its root again
2)and domain of the last , is [0,+infinity)
and for its range , you can draw it such as picture and will be [0,- infinity)
